Notes:

alberskib commented 10 years ago

@pablopareja In Gene onthology there is also next type of relationship: occurs_in but in model this kind of relationship is not present - it is something deprecated?

pablopareja commented 10 years ago

Hey! I just downloaded and checked out the last version of the OBO-XML file and there's no hit for that relationship. Where did you get that relationship type from?

alberskib commented 10 years ago

When you open file: http://geneontology.org/ontology/go.obo and search relationship: occurs_in you will find ie. entry with GO:0000963 id that has this relationship declared in file

pablopareja commented 10 years ago

You're right but so far we've been using the OBO-XML format; http://archive.geneontology.org/latest-termdb/go_daily-termdb.obo-xml.gz And there you cannot find any occurrence of that relationship... I have no idea why... One of them must be either wrong or outdated :confused:

alberskib commented 10 years ago

I also find occurs_in relationship in next file: http://purl.obolibrary.org/obo/go.owl. On next page http://www.geneontology.org/page/download-ontology OBO-XML is under legacy downloads section.

eparejatobes commented 10 years ago

@pablopareja @alberskib see Cross products in the GO docs. It's something that as far I know no tool relying on GO uses; kind of an experiment at this point.

eparejatobes commented 10 years ago

Also GO Ontology relations, this could be outdated though

alberskib commented 10 years ago

In the file http://purl.obolibrary.org/obo/go.owl. occurs_in can be found about 6 times in relationship tag and much more in intersection tag. To sum up which format is outdated?

eparejatobes commented 10 years ago

None of them :) it's the data. The standard GO distribution only considers the relations that we already have; all the others (like occurs_in) are part of the extended GO distribution.

alberskib commented 10 years ago

OK Great to know. Thanks
